> We have and issues with our Cassandra 3.0.5. After we deleted a large amount of data in the multiple partition keys. Query those partition keys with reversed order on a clustering key return the deleted data. I have checked and there are no tombstones left. All of them are deleted. So I don't know where or how can those deleted data still exist. Is there any other place that Cassandra will read data when query in reverse order compare to normal order ?
> the schema is very simple
> {noformat}
> CREATE TABLE table ( uid varchar, version timestamp, data1 varchar, data2 varchar, data3 varchar, data4 varchar, data5 varchar, PRIMARY KEY (uid, version, data1 , data2 , data3 , data4 ) ) with compact storage;
> {noformat}
> Query are doing reverse order on column timestamp
> Ex:
> {noformat}
> select * from data where uid="uid1" order by version DESC
> {noformat}
